Here are my comments on the draft of Occupational Intakes of radionuclides Part II.

First a general overview of Part II, it’s a fundamental publication and well done. This report and the following are expected by the profession and will be very useful for the interpretation of bioassay data.

The part II needs to be performed for the performance criteria for radiobiossays for each radionuclide in the chapter individual monitoring.

I have divided my comments into 2 groups

A – Important comments for modifications or changes

B – Technical comments for a need of additional explanations

A – Important comments for modifications or changes

In the whole document: the title of the Tables for individual monitoring are not identified (especially the detection limits).

In the whole document: there are confusions between typical detection limits and achievable detection limits. In the Part I, the criteria of the typical detection limits can be a range of values. For the achievable detection limits, it is obliged to be a value. In Part II, you can find a range for the achievable detection limits.
